Executive summary: The French tax authority suffered a major data leak, prompting politicians Lisnard and Knafo to demand the suspension of the mandatory electronic invoicing system planned to start on September 1, 2026.

Who is involved: French tax administration (DGFiP), politicians David Lisnard (Mayor of Cannes) and Aurore Knafo (MP), and approximately ten million VAT‑liable companies in France.
Likely next: The government may launch a cybersecurity review of the invoicing platform, potentially postponing the September 1 deadline or imposing stricter security standards before rollout.
